What is the test for a plaintiff to sue a local governmental entity for failing to comply with their obligations under the Civil Code of Civil Procedure?

To impose liability on a local governmental entity, a plaintiff must establish: (1) that he possessed a constitutional right of which he was deprived; (2) that the municipality had a policy; (3) that this policy "amounts to deliberate indifference" to the plaintiff's constitutional right; and (4) that the policy is the "moving force behind the constitutional violation."
